In this article I will endeavour to show how to detect colours with an Arduino connected to the TCS230/TCS3200 colour sensor.

The TCS3200 colour sensor can detect a wide variety of colours based on their wavelength. This sensor is specially useful for colour recognition projects such as colour matching, colour sorting, test strip reading and much more.

The working principle of an ultrasonic sensor is simple and use high-frequency sound waves that are evaluated when the sensor received back the waves. To determine the distance between the robot and object, the sensor measure the elapsed time between sending and receiving the waves.

With this tutorial, you will be learn to access any keypad, and have it interact with a microcontroller. You can salvage these keypads from old telephones or you can purchase them from most electronics store for less than $2. They come in wide variety of shapes and sizes. The most commons sizes are 3×4 and 4×4, and you can get keypads with with words, letters and numbers written on the keys.

There are a variety of development environments that can be used to program the ESP8266. The ESP8266 community created an add-on for the Arduino IDE that allows you to program the ESP8266 using the Arduino IDE and its programming language.

This Article aims to be a comprehensive guide to the popular RF 433MHz Transmitter/Receiver modules. Information on how they work, some features, and an Arduino project example that you can take and apply to other projects.

OpenElectrons.com have a new Arduino Shield being readied for release in the near future. You can use it to make Robots with ‘Arduino Brains‘, using either LEGO Mindstorms EV3 or NXT Motors, Sensors, and other Arduino compatible parts. If you wish, you can also attach a selection of available Arduino Shields on top of the EVShield.

I have just had 4 day up at Burnie on Tasmania’s North-west coast at the “Brixhibition Burnie” with my Robots. Among the robots I took was a OpenElectrons NXShield Powered Holonomic Platform which survived the abuse from the general public who where controlling it for some 18hrs, without it missing a beat.

I’m intending to use several Arduino Boards as a cheap means of controlling a number of RFID Readers which will be used to detect the position of Locomotive Engines on my LEGO Train Layout. That said I need a way of connecting these Arduinos to the Raspberry Pi which is the Master Controller for the layout.

The easiest way of Connecting an Arduino to a Raspberry PI is using USB, however the PI’s USB ports are need for WiFi Keyboard, Mouse, etc. So in many cases USB is out, especially if you are using a Raspberry Pi Model ‘A’.

OpenElectrons (Mindsensors) have released the NXShield which attaches directly to an Arduino. The NXShield allows you to connect NXT motors, NXT Sensors and RC Servo motors, along with I2C devices. Some NXShield versions have headers to connect other Arduino shields on top of the NXShield.

Isaac Asimov's "Three Laws of Robotics":

A robot may not injure a human being or, through inaction, allow a human being to come to harm. A robot must obey orders given it by human beings except where such orders would conflict with the First Law. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
